Be it knoivn that l.. GEORG' H. LYxnN,a citizen of the lnited States,residing at Passaic` in the county of Passaic and State of i New Jersey.have invented a new and useful Improvement in Apparatus for Use in theing in these chambers for a period of time,

'form a cakeor'mgssl of more or less `solid material. This material hasthe peculiarity of again becoming liquid or muddy. if disturbed oragitated 'in any mannerwhich will" cause friction between the particleslthereoij Owing'to' this peculiarity, it has been' very diiiicult toprovide 'satisfactory mechanicalvmeans or apparatus for emptying thesechambers,and the work. has gen-- erally been" done' by manual labor..This method, however, is objectionable owing to the injurious .effectson the operatives of the acid fumes in the chamber vand is -also eX-pensive.

The objects` of'this invention are to produce an apparatus by means ofwhich 'a the minimum labor and in' such a manner as to eliminate as far'as possible any stirring or agitation of the material; also to producean apparatus for this purpose which is .of

i strong, simple and rigid construction so that the parts thereof areWell able to resist the f strains to which they are subjected owing tothe weight of the material, and'also the cnrrosive actionof 'the' acidemployed in the manufacture of the superphosphate; also to improvethe'fconstruction of^apparatusofl -fied.

this kind Vin the respects hereinafter speci- In the accompanying.drawings, consisting of three sheets; Figurel is sectional view of adecomposing chamber showing in ele-. ration the-apparatus embodying.theinv'ention.

Briefly stated,1the apparatus comprises a'car-Which is adapted to bemoved into and the apparatus in plan. Fig-4 isa cross- `or cutters ofmodified construction. for re-v` to like out'of a decomposition chamberor den having walls which are adapted to engage with a L the :sides ofthe car to forma receptacle into l lwhich the material is poured whilein a liquid or'semi-liquid state. T he car is per= mitted to stand inthechamber or den until fied, whereupon the car carrying the.substantially solid cake is moved out of the knives or ,cutters arepreferably provided chamber and Wli'iclrare adapted to out the .cake ormass of material on the car and drop the material into suitable hoppersthrough Whichit may be fed to the conveyers or other means forremovingit.

` A represents a decomposition chamber or den, which :may be of anyusual or suitable 'a ceiling a2 provided with one or more tubesorf-conduits a3, by means of which the material -inA liquid state isdelivered to the chamber. A -tubeor Ventilating shaft a4 serves tol:onduct fumes and gases from the chamber. l afrepresen'ts a f iexibleVcurtain which serves to close thev open end of the chamber to preventthe escape of fumes and gases 4from the Chambon Acurtain of any suit'i'e'ceive the material, andvto be moved out,

the material has become suliciently solidi-1:

chamber to be emptied. Suitable sta tionary` outside of thedecomposition chamber, under which the car passes in moving out oftheconstructiom'having a floor a, walls a', and

able kind, 'or 'other lsuitable'v closure can' b employed. Instead ofdischarging -the inaterial from the tube a3 onto the floor of the'chamber A, as has heretofore' beendcne, a, movable 'support of anysuitable coustruction is prov1ded,.which isv adapted to be placed underthe tube 0,3 in `the chamber to ipa ofthe' chamber to beemptied. Thismovav ble support,='a s showxnis inthe form of a car B which, in orderto facilitate theempt'yilng i thereof, preferably has only a floor orplatform b and a rear wall'b, which may be sc ciired to the car in anysuitable manner.

The car body, as shown, is -mounted on wheelsb2 adapted to run oir trackrails b3.

The side land front walls which serve to 'retain the material on the carmaybe supported in operative relation to or in engagement with the carin any suitable manner. Since great strength is required in these Walls,to withstand the pressure thereon due to the weight'of the material, theWalls are preferably supported in any suitable manner .within thechamber.

In the construction shown in Figs. lthe side walls comprise two uprightplates C which are movably mounted in the chamber A to move into and outof engagement with the car, the -walls 'being mounted on wheels c whichrun on tilansverse rails c on the Hoor of the chamber A- and are movedtowardand from the ear by means of screwoperating devices VD. Each ofthescrewoperating devices shown, see Fig. 5, consists of a screwthrendedsleeve d engaging with af'scrcw d secured to the stationary wall a.' ofthe'chamtyer A. The sleeve is swiveled at d2 to a. 'plate or bearingmember-cl3 secured to themovable wall, and is provided with suitablehandles d* for 'turning it. Anv

;othersuitable Ameans could be employed for moving the Walls intoengagement With the -A 'ed to engage the 4inner faces of the movableside walls near the upper edge thereof, to

preventthe bending in of the side walls. Other meansh can be employedfor this' purose. p The front wall E of the car, in theconstructionshown, is pivoted at e on the side walls a, of thc chamber Aand is adapted to -be swung on its pivots into engagement with the carto close the front end thereof, and when it lis desired to remove thecar from the chamber the front wall can be swung upinto a horizontalposition (shown by d ottcd lines in Fig. l) abo-ve the mass of materialon the car, so as not' to interfere with the passage' of the materialbeneath it.

-The front wall, as shown, has a base portion v Q of the chamber. Thematerial remaining on e provided with holes for l bolts e2 for rigidlysecuring the Wallin place on the car. e3- indicates braces or ribsconnecting the wall and the base portion e thereof. 6*, Fig. 1,'represents 'suitable' hoisting tackle or other means for raising thefrontwall.

Any suitable means may be provided fog-i` moving the car into and out ofthe' decomn position chambersuch, for examplef-asgelf.

chain or cable F, Fig.' l, which is connected at its opposite ends tothe ,car and which passes around a suitable pulley f, located at one endof the chamber. The carcan be moved into or out of the chamber bydrawing the chain in either direction, which is preferably done by awindlass or other suitable device. Stationary shields or lates G. arepreferably providedbetween tlie mov'- able walls'- and the open side ofthe chamber, for preventing anv material which then delivered to the carand when it has become solidified. the side Walls are moved away fromthe car, preferably only enou h to avoid friction between the walls andtie cnr when the car .is being moved out of the chamber. The walls, whenin this position, act to prevent any parts of the' material, which mabreak othfrom falling on the floor of t e chamber. then swung into aposition to clear the car and the material thereon and the cer. can thenbe moved out of the chamber and emptied in any suitable manner. Ifthecar is to be emptied by hand, the front Wall need not be made removable,but vcould be rigidly secured to the' car as in thecase of the rearWall.

The material can be unloaded from the car in any convenientmanncr intosuitable hoppers o'r chutes H H, Figs. 1 and 3, which are located atopposite sides of the car andfrom which the material is discharged toa.suitable belt conveyer 7L or other transporting means. Preferably meansare provided for automatically unloading the car, consisting, in theconstruction shown, of a station-' ary knife or cutter I outsidev ofthedecomposition chamber. This cutter is so located relatively to the car,that the car, in moving out of the chamber, will pass under the cutter.The cutter, see Figs. l and 3, is wedge or plow-shaped and adapted tocut approximately into the middle ofthe cake of ma- The front Wall isleo terial on the car, and deflect the two-parts of the cake at oppositesides thereof side'- wise into the hoppers as the car vmoves out raralso converge in the same mannerso jected to no frictionV during itsmovement.

the rar and which may be employed-in place rl`his device.A comprises. a

the path 'otmovement ofthe cakeof ma'- terial, ,that each knife willremove a part i or slice o 't' the material on t-lie cai'.

- ln th-modified construction shown in F T and 8, the movable sidewalls, shown in l`igs. I-o, are dispensed with and the chamber -isprovided with stationary. plates L. which are-'seeured'to theside'wallsof .tlie saine the front wall is swunggintp itsl yhorizontal positionand the. first part of the'oiitward movement ofthe car serves thechamber Aand which converge toward the.

inner end of t he-chauiber. The sidesot the that the carcan be wedgedbetween the plates L to iorm a tight joint between the fioorof the carand the plates L. The front .wall`E\ can be placed in position on thecar as heretofore described Then the 'car is tobe moved out of thechamber for unloading to release 'the-cai' and the material thereon *theYmaterialis subjected in emptying the L. Thecar 'can then be movedout ofthe chamber A and unloaded as heretofore described. 'A

By means of the apparatus described the amount of lagitation andfriction to which chambers'is greatly reduced. 'lhe material is movedsidewise oft of the car and is subin .the chamber.' No labor is'required within the chamber eiicept to adjust the movable walls asdesired, and the costof emptying the dens,as'well :is the timerequiredfor this operation, are greatly'reduced by the use of thisapparatus.
